MODES FOR CARRYING OUT THE INVENTION

Hereinafter, a pouch according to exemplary embodiments of the presentinvention will be described in detail with reference to accompanyingdrawings.

First Exemplary Embodiment

As shown in FIGS. 1 to 3, a pouch 200 according to a first exemplaryembodiment includes a contents-accommodating section 210 having acontents-accommodating space S1 for accommodating contents; atemperature controller 220 placed in at least one side between a frontside and a rear side with respect to the contents-accommodating section210 in order to heat or cool the contents-accommodating section 210; anda sealing portion 230 sealing up a liquid reactant entrance 222communicating with temperature control spaces S2, S3 inside thetemperature controller 220.

Here, the contents may include food such as boiled rice, Bibimbap, soup,stew or dry milk; a pad containing medicine for taking a hot massage ora cold massage, or a mask pad containing beauty ingredients. Besides,the contents may be varied as long as it has to be instantly heated orcooled.

The contents-accommodating section 210 includes a first front film 211and a first back film 213 placed in front and back to form thecontents-accommodating space S1.

The first front film 211 and the first back film 213 may be made of aplastic film. In more detail, the plastic film may include polyethylene(PE), polypropylene (PP), or a polyethyelene terephthalate (PET).Besides, the first front film 211 and the first back film 213 may bemade of well-known synthetic resin films of various materials.

The temperature controller 220 couples with the contents-accommodatingsection 210, in more detail, couples with the contents-accommodatingsection 210 so as to form the temperature control spaces S2, S3 providedin at least one side between the front and rear sides with respect tothe contents-accommodating space S1.

FIGS. 1 to 3 illustrate that the temperature control spaces S2, S3 areformed in front and back, but not limited thereto. As necessary, thetemperature control spaces S2, S3 may be formed at only one side.

The temperature controller 220 includes a second front film 221 coupledin the front of the contents-accommodating section 210 and forming thetemperature control space S2 in a front side; and a second back film 224coupled in the back of the contents-accommodating section 210 andforming the temperature control space S3 in a back side.

The second front film 221 and the second back film 224 made of a plasticfilm such as polyethylene (PE), polypropylene (PP), or a polyethyeleneterephthalate (PET). Besides, the second front film 221 and the secondback film 224 may be made of well-known synthetic resin films of variousmaterials.

Here, the temperature control spaces S2, S3 are isolated from thecontents-accommodating space S1.

The front and back temperature control spaces S2, S3 can communicatewith each other through a communication space S4. The communicationspace S4 may be formed by arranging the contents-accommodating section210 so that the lower end portion 211 c of the contents-accommodatingsection 210 can be spaced apart from the lower end portion C1 of thetemperature controller 220. In this case, the lower end portion C1 ofthe temperature controller 220 is a part where the respective lower endportions of the second front film 221 and the second back film 224 arecoupled by ultrasonic waves or thermal welding. Of course, couplingbetween the plastic films may be achieved various well-known methodsbesides the foregoing ultrasonic waves or thermal welding.

Meanwhile, the contents-accommodating section 210 and the temperaturecontroller 220 may be coupled with each other at left and right endportions C1, C2 by ultrasonic waves or thermal welding.

The temperature controller 220 includes a plurality of temperaturecontrol agents 223, 225 respectively arranged in the plurality oftemperature control spaces S2, S3.

As described above, if the temperature control spaces S2, S3 are formedat only one side between front and back sides, the temperature controlagents 223, 225 may be arranged at only one corresponding side.

Here, the temperature control agents 223, 225 includes heating elements223 a, 225 a to exothermically react with the liquid reactant, andabsorption fabrics 223 b, 225 b surrounding the heating elements 223 a,225 a and absorbing the liquid reactant to make the exothermic reactionsmoothly.

As necessary, the absorption fabrics 223 b, 225 b may be omitted.

Also, a heat absorption agent endothermically reacting with the liquidreactant may be used instead of the heating elements 223 a, 225 a. Theheating element and the heat absorption agent react with the liquidreactant to heat and cool the contents accommodated in thecontents-accommodating space S1.

The heating element may include at least one among calcium oxide,calcium hydroxide, magnesium chloride, iron, and aluminum. Of course,the foregoing substances may be replaced or changed by other substancesas long as it can react with the liquid reactant.

The heat absorption agent may include at least one of ammonium nitrate(NH4NO3), sodium acetate and urea.

Here, the plurality of temperature control agents 223, 225 may allinclude only the heating elements, or only the heat absorption agent.

As necessary, in the plurality of temperature control agents 223, 225,the front temperature control agent 223 may include only the heatingelement, and the back temperature control agent 225 may include only theheat absorption agent. In this case, the front and back temperaturecontrol spaces S2, S3 may not communicate with each other but isolatedfrom each other with the contents-accommodating space S1 therebetween.

The temperature controller 220 may further include a liquid reactantentrance 222 through which the liquid reactant is put into thetemperature control spaces S2, S3.

The liquid reactant entrance 222 is to put the liquid reactant capableof reacting with the temperature control agents 223, 225.

The liquid reactant entrance 222 is sealed up but openable in thesealing portion 230 to be described later.

Also, the liquid reactant entrance 222 is arranged at a lower side ofthe contents-accommodating section 210 rather than an upper end thereof.That is, an upper edge of the liquid reactant entrance 222 is lower thanthe upper end of the contents-accommodating section 210 so that a usercan easily check the position of the liquid reactant entrance 222 withhis/here naked eyes.

The liquid reactant entrance 222 may be formed as a partial upper endsection G of the second front film 221 of the temperature controller 220is not coupled with the first front film 211. At this time, the secondfront film 221 of the remaining upper end section C3 may be permanentlysealed up with the first front film 211.

Here, the drawings illustrate the liquid reactant entrance 222 is formedin the partial upper end section G of the second front film 221. Asnecessary, the liquid reactant entrance 222 may be formed in the entireupper end section of the second front film 221.

Also, the height of the liquid reactant entrance 222 from the lower endof the pouch may be relatively greater than that of the remainingsection C3 of the second front film 221 from the lower end of the pouch.Of course, the liquid reactant entrance 222 may have the same height asthe remaining section C3 of the second front film 221.

The liquid reactant entrance 222 may include a grip portion extendedfrontward to be griped by a user's hand. Thus, a user can easily openthe liquid reactant entrance 222.

Here, the grip portion 222 a may be as shown in FIG. 3 formed to befolded down from the first front film 211.

As necessary, instead of the grip portion 222 a of FIG. 3, the upper endof the second front film 221 may be as shown in FIG. 4 provided as it isspaced from the contents-accommodating section 210, specifically fromthe first front film 211 by a predetermined space K. Thus, a user putshis/her fingers in the space K and broadens the liquid reactant entrance222, thereby opening the liquid reactant entrance 222.

Meanwhile, the sealing portion 230 seals up the liquid reactant entrance222. Thus, it is possible to prevent foreign materials from entering theliquid reactant entrance 222 while the contents is put into andsterilized in the contents-accommodating section S1 of the pouch 200.Such sterilization is essential when a retort pouch is produced byputting stew, soup, boiled rice and the like instant foods into thepouch 200.

Accordingly, the pouch 200 according to an exemplary embodimentfacilitates the manufacture of the retort pouch.

As shown in FIG. 3, the sealing portion 230 may be provided between thesecond front film 221 and the first front film 211 at a side lower thanthe grip portion 222 a of the liquid reactant entrance 222.

The sealing portion 230 may be provided to allow opening between thefirst front film 211 and the second front film 221 when force of notless than a predetermined magnitude is applied thereto. In other words,if external force of not less than a predetermined magnitude is applied,the sealing portion 230 may open the liquid reactant entrance 222. Thus,if a user grips and then pulls the grip portion 222 a by force of notless than a predetermined magnitude, the liquid reactant entrance 222 isopened.

A user puts the liquid reactant (for example, water) into the openedliquid reactant entrance 222, thereby heating or cooling the contentsaccommodated in the contents-accommodating space S1.

In particular, it is convenient for a user because the liquid reactantentrance 222 is easily opened to put the liquid reactant therein.

The sealing portion 230 may include an adhesive or a double-sided tape.As necessary, the sealing portion 230 may be formed by fusing the firstfront film 211 and the second front film 221 through thermal welding orultrasonic waves. At this time, the first front film 211 and the secondfront film 221 may be fused to such an extent as to be separated fromeach other when the sealing portion 230 receives external force of apredetermined magnitude.

Of course, the sealing portion 230 may be varied as long as it can sealup the liquid reactant entrance and prevent foreign materials, such asliquid (e.g., water), from being introduced therein if there is noexternal force of not less than a predetermined magnitude.

Meanwhile, the pouch 200 may further include a ziplock 260 toselectively seal up the upper portion of the contents-accommodatingsection 210.

The ziplock 260 includes a female zipper 261 formed inside the firstfront film 211 and a male zipper 263 formed inside of the first backfilm 213. Of course, the positions of the female zipper 261 and the malezipper 263 may be exchanged.

Also, various well-known sealing means may be employed instead of theziplock 260 as long as it can selectively seal up thecontents-accommodating section 210.

Meanwhile, the pouch 200 may further include a transparent window 215,216, 217 for checking whether the contents-accommodating space S1 issealed up or not. That is, the defect of the contents-accommodatingsection 210 can be determined by naked eyes through the transparentwindows 215, 216, 217.

As shown in FIG. 1, the transparent window 215 may be arranged betweenthe liquid reactant entrance 222 and the upper end of the first frontfilm 211. Through the transparent window 215, contact between the firstfront film 211 and the contents accommodated therein is checked by nakedeyes, and it is thus possible to determine whether a product isdefective or not. For example, if solid food is put into thecontents-accommodating section 210 and then the contents-accommodatingspace S1 is vacuumized, it is possible to determine by naked eyesthrough the transparent window 215 whether there is a trouble in thevaccumization.

Meanwhile, the transparent window 216 may be as shown in FIGS. 1 and 2formed in a lower portion of the pouch 200. If the contents accommodatedin the contents-accommodating section 210 is liquid and the liquid leaksout because the contents-accommodating section 210 is defective, it ispossible to determine by naked eyes through the transparent window 216of the lower portion whether the product is defective or not. To make iteasier to determine through the transparent window 216 of the lowerportion whether the contents-accommodating section 210 is sealed up ornot, a corresponding region of the second front film 221 formed with thetransparent window 216 may be transparently formed, but a correspondingregion of the first front film 221 may be opaque. For example, thesecond front film 221 may be entirely made of a transparent film, whilethe first front film 221 may be entirely made of an opaque film.

Also, the transparent window 217 formed in a vertical direction may beas shown in FIG. 1 formed at one side between left and right sides ofthe pouch 200 along a lengthwise direction. Thus, a user leans the pouch200 and checks by his/her naked eyes through the transparent window 217whether the contents accommodated in the contents-accommodating section210 leak out or not, thereby determining whether a product is defectiveor not.

The plurality of transparent windows 215, 216, 217 are to check whetherthe contents-accommodating space S1 of the contents-accommodatingsection 210 is surely isolated from the temperature control spaces S2,S3. If it is checked through the plurality of transparent windows 215,216, 217 that there is no defect in a product, the contents of thecontents-accommodating space S1 is not affected by a byproduct producedby the exothermic or endothermic reaction within the temperature controlspaces S2, S3.

The drawings show the plurality of transparent windows 215, 216, 217,but the number and positions of the transparent windows 215, 216, 217may be varied.

Meanwhile, the foregoing description illustrates that the liquidreactant entrance 222 is formed at only one side between the front andback sides, but not limited thereto. Alternatively, the liquid reactantentrance 222 may be formed at both the front and back sides.

Second Exemplary Embodiment

Meanwhile, a pouch 200 a according to the second exemplary embodimentmay as shown in FIG. 5 include a contents-accommodating section 210 a, atemperature controller 220 and a sealing portion 230.

The contents-accommodating section 210 a of the pouch 200 according tothe first exemplary embodiment has the lower end 211 c spaced apart fromthe lower end of the temperature controller 220 as shown in FIG. 3. Onthe other hand, in the pouch 200 a according to the second exemplaryembodiment, as shown in FIG. 5, the lower end of thecontents-accommodating section 210 a is extended to the lower end of thetemperature controller 220 so that the contents-accommodating section210 a and the temperature controller 220 can be coupled with each otherin a lower region by ultrasonic waves or thermal welding.

A communication hole 211 b, 213 b may be formed in thecontents-accommodating section 210 a so that the front and backtemperature control spaces S2, S3 can communicate with each other. Here,the edge of the communication hole 211 b, 213 b is sealed up to preventthe contents accommodated in the contents-accommodating space S1 fromleaking out through the communication hole 211 b, 213 b.

Third Exemplary Embodiment

A pouch 200 b according to the third exemplary embodiment may as shownin FIGS. 6 and 7 include a contents-accommodating section 210, atemperature controller 220 and a sealing portion 240.

According to the third exemplary embodiment, the contents-accommodatingsection 210 and the temperature controller 220 except the sealingportion 240 are the same as those of the first exemplary embodiment.

According to the third exemplary embodiment, the sealing portion 240 mayinclude an adhesive tape 240 to seal up the upper end of the liquidreactant entrance 222. Thus, it is possible to prevent foreign materials(in particular, liquid) from being introduced into the temperaturecontrol spaces S2, S3 while the contents are put into thecontents-accommodating section S1 and sterilized after the upper end ofthe contents-accommodating section S1 is sealed up.

Meanwhile, the adhesive tape 240 includes an extended portion 241extended so that one side there of can be gripped. Thus, a user caneasily put the liquid reactant into the pouch 200 b by pulling theextended portion 241 and removing the adhesive tape 240.

The transparent window 253 may be formedby making at least one region of the pouch stand 250 with a transparentsubstance. As necessary, the pouch stand 250 may be entirely made of atransparent substance. Thus, a user can determine whether a product isdefective or not with his/her naked eyes through the transparent window253 formed on the bottom of the pouch 200 c.

When the contents-accommodating section 210 is filled with the contents,the lower portion of the contents-accommodating section 210 may beexpanded toward the pouch stand 25. In more detail, the lower portion ofthe contents-accommodating section 210 is creased so that thecontents-accommodating section 210 can expand toward the pouch stand 25when the contents-accommodating section 210 is filled with the contents.

Also, the lower portion of the contents-accommodating section 210 isarranged near to the inside of the pouch stand 25 so that both the pouchstand 25 and the contents-accommodating section 210 can expand towardthe bottom supporting the pouch 200 by the weight of the contentsaccommodated in the contents-accommodating section 210.

In more detail, oneend and the other end of the inner bottom film 218 are respectivelysealed and coupled to the lower end of the first front film 211 b andthe lower end of the first back film 213 b, thereby forming thecontents-accommodating section 210 b. The inner bottom film 218 surelysecures a lower space of the contents-accommodating section 210 b sothat the contents-accommodating space S1 can be filled with morecontents.

Sixth Exemplary Embodiment

FIG. 10 is a perspective view of a pouch according to the sixthexemplary embodiment, FIG. 11 is a section view, taken along line A2-A2of FIG. 10, FIG. 12 is a section view showing that the pouch shown inFIG. 11 is filled with the temperature controllable object, and FIG. 13is a section view showing that a sealing portion is opened to put aliquid reactant into the temperature control space of the pouch shown inFIG. 11.

As shown in FIGS. 10 to 13, a pouch 100 according to the sixth exemplaryembodiment includes an accommodating section 110, a temperaturecontroller 130 provided with a temperature control agent 131, a sealingportion 140, a grip portion 150, a supporter 160, a sealing-barattachment-preventing portion 170 and a cutting portion 180.

The pouch 100 according to the sixth exemplary embodiment does notinclude the temperature control agent 131 and the liquid reactant W forthe exothermic or endothermic reaction. That is, the liquid reactant Wis put into the pouch 100 from the outside in order to control thetemperature of the temperature controllable object 10.

Here, the temperature controllable object 10 includes various instantfood such as the retort pouch. For example, the contents may includefood such as boiled rice, Bibimbap, soup, stew or dry milk; a padcontaining medicine for taking a hot massage or a cold massage, or amask pad containing beauty ingredients. Besides, the contents may bevaried as long as it has to be instantly heated or cooled.

The accommodating section 110 includes a first accommodating sectionfilm 112 and a second accommodating section film 114. An accommodatingspace 116 for accommodating the temperature controllable object 10 isformed between the first accommodating section film 112 and the secondaccommodating section film 114. Here, the first accommodating sectionfilm 112 and the second accommodating section film 114 may be made of aheat-resistant plastic film.

In more detail, the accommodating section 110 may be made of the plasticfilm such as polyethylene (PE), polypropylene (PP), or a polyethyeleneterephthalate (PET). Of course, the first accommodating section film 112and the second accommodating section film 114 constituting theaccommodating section 110 may be made of well-known synthetic resinfilms of various materials.

For example, the first accommodating section film 112 may include a CPPfilm having a thickness of 60 μm, an aluminum film having a thickness of9 μm, or a combination film between a nylon film having a thickness of15 μm and a CPP film having a thickness of 60 μm. Of course, this isnothing but illustrative. The first accommodating section film 112 mayinclude a combination film of various materials, or as necessary includea film of a single material. The second accommodating section film 114may be made of the same material as that of the first accommodatingsection film 112.

The first accommodating section film 112 and the second accommodatingsection film 114 form an envelope shape as the other side and both sidesconnecting one side and the other side are adhered and sealed so as toopen one side. As the first accommodating section film 112 and thesecond accommodating section film 114 are adhered, the accommodatingspace 116 accommodating the temperature controllable object 10 isformed. Trough an opening side of the accommodating section 110, thetemperature controllable object 10 is filled in the accommodating space116, and the opening side is sealed up by the sealing-barattachment-preventing portion 170 to be described later after thetemperature controllable object 10 is completely filled.

The temperature controller 130 may be formed at one side between bothsides of the accommodating section 110. The temperature control agent131 is accommodated in between the temperature controller 130 and theouter side of the accommodating section 110, and exothermally orendothermally reacts with the liquid reactant w to be inserted, therebyheating or cooling the temperature controllable object 10.

The temperature controller 130 according to the sixth exemplaryembodiment includes the temperature control agent 131 arranged at leastone side between front and back sides of the accommodating section 110and heating or cooling the temperature controllable object (i.e., thecontents); and a temperature control space forming member 132 providedin a lower side of the accommodating section 110 rather than an upperside thereof, having the liquid reactant entrance 136 through which theliquid reactant w is inserted, and forming a temperature control space134 where the exothermic or endothermic reaction occurs.

The temperature control agent 131 includes a reactant 131 b and areactant accommodating section 131 a. According to the sixth exemplaryembodiment, the temperature control agent 131 is arranged at one sidebetween both sides of the accommodating section 110. The temperaturecontrol agent 131 may be arranged at a side facing the firstaccommodating section film 112. The temperature control agent 131 reactswith the liquid reactant w such as water inserted from the outside.

The reactant 131 b includes the heating element or the heat absorptionagent in accordance with whether to heat or cool the temperaturecontrollable object 10 accommodated in the accommodating section 110.The reactant 131 b may include at least one as the heating element amongcalcium oxide (CaO), calcium hydroxide (Ca(OH)2), magnesium chloride(MgCl2), iron (Fe) and aluminum (Al). Here, the reactant 131 b may bereplaced or changed by other substances as long as it can exothermallyreact with the liquid reactant w.

On the other hand, the reactant 131 b may include at least one as theheat absorption agent among ammonium nitrate (NH4NO3), sodium acetate(CH3COONa) and (urea). Of course, the reactant 131 b may be replaced orchanged by other substances as long as it can endothermally react withthe liquid reactant w.

The reactant accommodating section 131 a accommodates the reactant 131b. The reactant accommodating section 131 a includes a body 131 a 1 anda partition 131 a 2. The reactant accommodating section 131 a isprovided as an absorption fabric to quickly absorb the liquid reactantw. As necessary, the reactant accommodating section 131 a may be made ofnot the absorption fabric but other substances.

The body 131 a 1 is provided to accommodate the reactant 131 b. Here,the body 131 a 1 according to an exemplary embodiment is partitionedinto four accommodating regions by the partition 131 a 2. Thus, thereactant 131 b is accommodated in each of the plurality of accommodatingregions partitioned by the partition 131 a 2, thereby preventing thereactant 131 b from being leaning by its own weight. Also, the reactant131 b is accommodated in each of the plurality of accommodating regions,and thus the divided reactant 131 b individually contacts the liquidreactant w, thereby making a temperature control reaction quickly.

The temperature control space forming member 132 together with the firstaccommodating section film 112 forms the temperature control space 134to accommodate the temperature control agent 131. The temperaturecontrol space 134 is a space where the exothermic or endothermicreaction occurs when the liquid reactant w is inserted, and has a marginspace to accommodate the liquid reactant w in addition to thetemperature control agent 131.

Here, the temperature control space forming member 132 may be made of atransparent synthetic resin film so that the liquid reactant w and thetemperature control agent 131 to be inserted can be checked by nakedeyes. Of course, the temperature control space forming member 132 may bepartially made of the transparent synthetic resin film checkable bynaked eyes. Of course, checkability by naked eyes is optional, and thusan opaque film may be used as necessary. The temperature controller 130may be provided smaller than the accommodating section 110 so that anupper opening of the accommodating section 110 for inserting thetemperature controllable object 10 can be exposed. According to anexemplary embodiment, the height of the temperature control spaceforming member 132 may be eight tenth with respect to the height of theaccommodating section 110.

The temperature control space forming member 132 may have an upper endlower than that of the contents-accommodating section 110.

The temperature control space forming member 132 may be made of theplastic film. For example, the temperature control space forming member132 may be the plastic film where a PET film having a thickness of 12 μmand a CPP film having a thickness of 60 μm are combined. Of course, thisis nothing but illustrative. Alternatively, the plastic film may be acombination film where films of various well-known substances arecombined or a single material film.

Meanwhile, the temperature controller 130 adjacent to the opening of theaccommodating section 110 includes a liquid reactant insertion portion136 for opening and closing the temperature control space 134 to insertthe liquid reactant therethrough. The liquid reactant insertion portion136 is coupled to the contents-accommodating section 110 by the sealingportion 140 to be described later, and seals up the temperature controlspace 134.

The liquid reactant insertion portion 136 may be spaced part from thesealing portion 140 or the first accommodating section film 112 whenforce of not less than a predetermined magnitude is applied forinserting the liquid reactant w in the temperature control space 134.Thus, the upside of the temperature control space 134 is opened so thatthe liquid reactant w can be inserted in the temperature control space134.

The sealing portion 140 seals up the accommodating section 110 and thetemperature controller 130, specifically, the liquid reactant insertionportion 136, thereby sealing up the temperature control space 134. Here,the sealing portion 140 seals up the accommodating section 110 and theliquid reactant insertion portion 136 with predetermined intensity ofadhesion so that the temperature control space 134 can be opened whenforce of not less than a predetermined magnitude is applied for spacingthe liquid reactant insertion portion 136 apart from the accommodatingsection 110. That is, when the liquid reactant insertion portion 136 ispulled by force of not less than a predetermined magnitude strong enoughto overcome the adhesion, the temperature control space 134 is opened.On the other hand, if force of not less than a predetermined magnitudeis not applied, the sealing is maintained so that foreign materialsincluding the liquid reactant cannot be introduced into the temperaturecontrol space 134.

Here, the sealing portion 140 may have an adhesive strength of not lessthan 200 gf/cm² and not more than 5 kgf/cm². In experimental results, ifthe adhesive strength is less than 200 gf/cm², the sealing may not bemaintained when the temperature controllable object 10 is filled andthen heated to expand the temperature control space 134. On the otherhand, the adhesive strength is more than 5 kgf/cm², it is difficult fora regular adult to open the temperature control space 134.

Preferably, the sealing portion 140 may have a adhesive strength of 500gf/cm²˜3 kgf/cm².

According to an exemplary embodiment, the sealing portion 140 is placedon the planar surface of the first accommodating section film 112, andseals up between the liquid reactant insertion portion 136 of thetemperature controller 130 and the first accommodating section film 112.Thus, the sealing portion 140 seals up between the first accommodatingsection film 112 and the liquid reactant insertion portion 136, andprevents foreign materials from being introduced into the temperaturecontrol space 134 while the temperature controllable object 10 is filledin the accommodating space 116 of the accommodating section 110 and thensterilized. Such sterilization is essential when a retort pouch isproduced by putting stew, soup, boiled rice and the like instant foodsinto the pouch 100.

Meanwhile, the sealing portion 140 may be released from the sealing withthe liquid reactant insertion portion 136 when force of not less than acertain magnitude is applied for inserting the liquid reactant w intothe temperature control space 134 as temperature control is required forthe temperature controllable object 10. Then, the liquid reactantinsertion portion 136 is opened to open the temperature control space134, so that the liquid reactant w can be inserted in the temperaturecontrol space 134. Accordingly, the exothermic or endothermic reactionoccurs between the temperature control agent 131 and the liquid reactantw.

Here, the sealing portion 140 may include at least one among liquidadhesive for adhering the first accommodating section film 112 and theliquid reactant insertion portion 136, a solid adhesive tape, and aneasy peel film provided between the first accommodating section film 112and the liquid reactant insertion portion 136.

Here, the solid adhesive tape may be a film type tape, one or both sidesof which the adhesive is applied to.

The easy peel film couples both films thereof with predetermine thermaladhesion when heat of a predetermined temperature range is applied.Here, the coupling force or adhesion may be controlled by adjusting thetemperature range of heat applied to the easy peel film.

Here, the adhesive strength due to the sealing portion 140 between theliquid reactant entrance 136 and the accommodating section 110 is weakerthan contact strength between the temperature control space formingmember 132 and the accommodating section 110 besides the liquid reactantentrance 136.

In more detail, the liquid reactant entrance 136 is expected to beopened so as to insert the liquid reactant in the temperature controlspace 134, and therefore the adhesive strength of the partial sealingportion C6 between the liquid reactant entrance 136 and theaccommodating section 110 may be weaker than the adhesive strength ofthe partial sealing portion C7 in a lateral edge between the temperaturecontrol space forming member 132 and the accommodating section 110. Thismay be achieved by changing the temperature range of the sealing barused when sealing the partial sealing portions C7, C6. Such temperaturerange will be described later.

Meanwhile, the grip portion 150 is provided to grip the liquid reactantinsertion portion 136 of the temperature controller 130. The gripportion 150 is extended from the liquid reactant insertion portion 136and formed integrally with the liquid reactant insertion portion 136.

The grip portion 150 may protrude from the liquid reactant insertionportion 136. The grip portion 150 may be provided in a center region ofthe liquid reactant insertion portion 136. The grip portion 150protrudes from the center region of the liquid reactant insertionportion 136 and is gripped by a user. In particular, the grip portion150 is gripped by a user and transfers a user's force to the liquidreactant insertion portion 136 so that the liquid reactant insertionportion 136 can be released from the accommodating section 110. To makea user easily grip the grip portion 150 and efficiently transfer his/herforce, the grip portion 150 may protrude from the center portion of theliquid reactant insertion portion 136.

Of course, the grip portion 150 may be provided at both sides of theliquid reactant insertion portion 136.

The supporter 160 is provided in at least one of the outer side of theaccommodating section 110 forming the temperature control space 134 andthe inner side of the temperature controller 130. The supporter 160supports the temperature control agent 131 in the temperature controlspace 134 and prevents the temperature control agent 131 from moving.That is, the supporter 160 prevents the temperature control agent 131from moving during a distribution process of the pouch 100. Thesupporter 160 is not essential for the pouch 100, and may be omitted asnecessary.

According to an exemplary embodiment, the supporter 160 is placed on aninner side of the temperature control space forming member 132 andsupports the temperature control agent 131. Of course, the supporter 160may be placed on an outer side of the first accommodating section film112 and support the temperature control agent 131. The supporter 160 maybe made of various adhesive materials such as the adhesive tape in orderto support the temperature control agent 131 against the temperaturecontrol space forming member 132.

Meanwhile, when the sealing-bar attachment-preventing portion 170 sealsup the upper ends of the first accommodating pack film 112 and thesecond accommodating pack film 114 by the sealing bar 131 a 2 having apredetermined sealing temperature in order to seal up the upper side ofthe accommodating section 110, the first accommodating pack film 112 isattached to and not separated from the sealing bar.

In more detail, the first accommodating pack film 112 is as describedabove made of a single CPP film or a combination film where the CPP filmis exposed. The CPP film may be attached to and not well separated fromthe sealing bar, and to prevent this, the sealing-barattachment-preventing portion 170 may be provided in the accommodatingsection 110 contacting the sealing bar.

The PET substance may be used as a material not well attached to thesealing bar. The sealing-bar attachment-preventing portion 170 mayinclude a film of which a part exposed frontward is combined with thePET film, or a single PET film.

For example, the sealing-bar attachment-preventing portion 170 may bethe same plastic film as the temperature control space forming member132, where the PET film having a thickness of 12 μm and the CPP filmhaving a thickness of 60 μm are combined. Here, the PET film has to bearranged to be exposed frontward so that the PET film can contact thesealing bar.

Here, it is just illustrative that the PET is used as a material for thesealing-bar attachment-preventing portion 170. The PET may be replacedby the plastic films of various well known materials as long as itcannot well attached to the sealing bar.

The cutting portion 180 is provided between the liquid reactantinsertion portion 136 and the sealing-bar attachment-preventing portion170.

The cutting portion 180 may include a notch cut in a transversedirection at one or both sides of the accommodating section 110 so thatthe accommodating section 110 can be torn when transverse force of notless than a certain magnitude is applied.

The cutting portion may be so thin that the portion cut by the notch canbe easily torn.

As shown in FIG. 11, since the first accommodating section film 112 andthe second accommodating section film 114 exist in the cutting portionAA1 formed with the notch, it is thinner than three layered films of thesealing-bar attachment-preventing member 170, and the first and secondaccommodating section films 112, 114 placed above the accommodatingsection 110.

Also, total four layered films of the temperature control space formingmember 132, the sealing portion 140, the first accommodating sectionfilm 112 and the second accommodating section film 114 exist below thecutting portion AA1, and therefore the cutting portion AA1 having totaltwo layered films is relatively thin. Thus, the cutting portion AA1 canbe more easily torn.

Meanwhile, the supporter 160, the sealing-bar attachment-preventingportion 170 and the cutting portion 180 described above are notessential, and all or a part of them 160, 170, 180 may be omitted asnecessary.

Meanwhile, the foregoing illustrates that the lateral edges C7 of thefirst accommodating section film 112 and the second accommodatingsection film 114 of the accommodating section 110 are directly sealedup. As necessary, the cross section of the lateral edges may be creasedlike “

” so that a user can more easily grip the lateral side of the pouch 100.This may be achieved by interposing a separate film between the lateraledges of the first accommodating section film 112 and the secondaccommodating section film 114 and thus broadening both edges.

Here, among theelements of the pouch 300 according to the seventh exemplary embodiment,the accommodating section 110, the temperature control agent 131, thesupporter 160, the sealing-bar attachment-preventing portion 170 and thecutting portion 180 are the same as those of the sixth exemplaryembodiment, and thus repetitive descriptions thereof will be avoided.

The temperature controller 330 includes a first temperature controlspace forming member 331, a second temperature control space formingmember 332, a first liquid reactant insertion portion 337 and a secondliquid reactant insertion portion 338. The first temperature controlspace forming member 331 and the second temperature control spaceforming member 332 respectively accommodate the first accommodatingsection film 112 and the second accommodating section film 114. Betweenthe first temperature control space forming member 331 and the secondtemperature control space forming member 332 and between the firstaccommodating section film 112 and the second accommodating section film114 are formed the first temperature control space 334 and the secondtemperature control space 335, respectively. Here, each of the firsttemperature control space 334 and the second temperature control space335 accommodate the temperature control agent 131.

Further, the upper regions of the first temperature control spaceforming member 331 and the second temperature control space formingmember 332 are provided with the first liquid reactant insertion portion337 and the second liquid reactant insertion portion 338 to open andclose the temperature control spaces 334, 335, respectively.

The sealing portion 340 is provided to allow the first liquid reactantinsertion portion 337 and the second liquid reactant insertion portion338 to seal up the first temperature control space 334 and the secondtemperature control space 335, respectively. The sealing portion 340includes the first sealing portion 342 for sealing up between the firstaccommodating section film 112 and the first liquid reactant insertionportion 337, and a second sealing portion 344 for sealing up between thesecond accommodating section film 114 and the second liquid reactantinsertion portion 338. Here, the first sealing portion 342 and thesecond sealing portion 344 may include the liquid adhesive or the solidadhesive tape or the easy peel film like the sealing portion 140according to the sixth exemplary embodiment.

The grip portion 350 includes a first grip portion 352 and a second gripportion 354 to be gripped so that the first liquid reactant insertionportion 337 and the second liquid reactant insertion portion 338 canopen the first temperature control space 334 and the second temperaturecontrol space 335, respectively. The first grip portion 352 may beplaced in the center region of the first liquid reactant insertionportion 337, and the second grip portion 354 may be placed in the centerregion the second liquid reactant insertion portion 338. The first gripportion 352 and the second grip portion 354 have the same shape as thatof the grip portion 150 according to the sixth exemplary embodiment. Ofcourse, the first grip portion 352 and the second grip portion 354 mayhave a different shape from the grip portion 150 according to the sixthexemplary embodiment.

As described above, the pouch 300 according to the seventh exemplaryembodiment accommodates two temperature control agents 131 in twotemperature control spaces 334, 335 on the contrary to the sixthexemplary embodiment, and thus can more quickly control the temperatureof the temperature controllable object 10 than the pouch 100 accordingto the sixth exemplary embodiment.

Eighth Exemplary Embodiment

FIG. 16 is a perspective view of a pouch according to an eighthexemplary embodiment.

A pouch 500 according to the eighth exemplary embodiment as shown inFIG. 16 includes a grip portion 550 different from those of the pouches100, 300 according to the first and seventh exemplary embodiments.

The grip portion 550 according to the eighth exemplary embodimentincludes a grip body 552 and a cutting line 554. The grip body 552 isprovided in a transverse direction of the drawing at the upper openingof the temperature control space 134, that is, a region to be sealed upby the sealing portion 140. The cutting line 554 is provided to open thetemperature control space 134 when force of not less than a certainmagnitude is applied to the grip body 552. That is, the cutting line 554is removed from the temperature controller 130 when transverse force isapplied to the grip body 552, and opens the temperature control space134.

Here, in the pouch according to the eighth exemplary embodiment, foreignmaterials may enter the temperature control space 134 through thecutting line 554 during a sterilization process. Therefore, the pouchaccording to the eighth exemplary embodiment can be used when there isno need of the sterilization process after the temperature controllableobject (i.e., the contents) is filled in the accommodating section 110of the pouch 500. For example, if the temperature controllable object(i.e., the contents) is solid dried food or a liquid or solid beautyproduct, the sterilization process may be not needed.

Here, a partial region of the grip body 552 may protrude from theaccommodating section 110 so that a user can easily grip it.

The grip portion 550 according to the eighth exemplary embodiment isprovided with the cutting line 554 at the opening side of thetemperature controller 130, thereby improving the sealing of thetemperature control space 134 and convenience when opening thetemperature control space 134.

Ninth Exemplary Embodiment

Lastly, FIG. 17 is a section view of a pouch according to a ninthexemplary embodiment.

The pouch 700 according to the ninth exemplary embodiment may be appliedto the pouches 100, 300, 500 according to the first to eighth exemplaryembodiments. The pouch 700 according to the ninth exemplary embodimentincludes a pouch stand 790 so as to make the accommodating section 110stand.

The pouch stand 790 according to an exemplary embodiment is providedbetween the first accommodating section film 112 and the secondaccommodating section film 114 of the accommodating section 110. Here,the pouch stand 700 may be made of a film thickener than the firstaccommodating section film 112 and the second accommodating section film114 constituting the accommodating section 110. Of course, the pouchstand 790 may be placed between the accommodating section 110 and thetemperature controller 130, but may be placed between the firstaccommodating section film 112 and the second accommodating section film114 constituting the accommodating section 110 according to an exemplaryembodiment in order to stably keep a standing state the pouch 700.

Thus, the pouch stand 790 is provided to make the pouch 700 stand, sothat the temperature control for the temperature controllable objectinside the pouch 700 can be stably performed.

Tenth Exemplary Embodiment

A pouch 100 a according to a tenth exemplary embodiment as shown in FIG.18 to FIG. 20 includes an accommodating section 110; a temperaturecontroller 130 including a temperature control agent 131, a liquidreactant entrance 136 and a temperature control space forming member132; a sealing portion 140, a cutting portion 180 and a pouch stand 790.

The pouch 100 a according to the tenth exemplary embodiment does notinclude the supporter 160 and the sealing-bar attachment-preventingportion 170 as compared with that 100 of the sixth exemplary embodiment.

As shown in FIG. 19, in the state that the upper end portions of thefirst and second accommodating section films 112, 114 are not sealed upand the upper portion of the accommodating section 110 is being opened,the temperature controllable object 10 is inserted in the accommodatingsection 110 along an inserting direction D.

To heat or cool the temperature controllable object 10 accommodated inthe accommodating section 110, a user first grips the grip portion 150as shown in FIG. 21, and pulls the liquid reactant entrance 136 in adirection F, thereby spacing it apart from the accommodating section110. At this time, if force of not less than a predetermined magnitudeis applied for spacing the liquid reactant entrance 136 apart from theaccommodating section 110, the liquid reactant entrance 136 is opened.As described above, the thermal adhesive strength in the sealing regionC6 due to the sealing portion 150 is weaker than the thermal adhesivestrength of the edge portion C7 of the accommodating section 110, andtherefore the liquid reactant entrance 136 can be more easily openedthan other portions.

In the state that the temperature control space 134 is being opened, theliquid reactant is inserted in a direction H. Accordingly, theexothermic or endothermic reaction occurs between the liquid reactantand the temperature control agent 131 within the temperature controlspace 134, and thus the temperature controllable object 10 accommodatedin the accommodating space 116 is heated or cooled.

After a lapse of predetermined time, a user uses the grip portion 180 tocut open the upper end of the accommodating section 110. Thus, a usertakes in, takes out or uses the heated or cold temperature controllableobject 10 through the accommodating section 110 having the opened upperportion.

Sixteenth Exemplary Embodiment

A pouch 100 c according to a sixteenth exemplary embodiment as shown inFIG. 27A and FIG. 27B includes the accommodating section 110accommodating the temperature controllable object; the temperaturecontroller 130; the sealing portion 140; the grip portion 150; the pouchstand 790 and a spout cap 170.

The pouch 100 c according to the sixteenth exemplary embodiment does notincludes the cutting portion 180, the supporter 160 and the sealing-barattachment-preventing portion 170 as compared with the pouch accordingto the sixth exemplary embodiment.

The pouch 100 c according to the sixteenth exemplary embodiment includesthe spout cap 170 instead of the cutting portion (refer to 180 in FIG.1). If there is the cutting portion (refer to 180 in FIG. 1) like thesixth exemplary embodiment, a user cuts the cutting portion (refer to180 in FIG. 1) and opens the accommodating section 110, thereby takingin or using the temperature controllable object 10 a filled therein. Onthe other hand, in the eleventh exemplary embodiment, a user opens thespout cap 170 instead of cutting the cutting portion (refer to 180 inFIG. 1) and then takes in the temperature controllable object 10 a.

Here, the spout cap 170 may be replaced by a straw hole (not shown) forreceiving a straw and a soft tape attached to the hole. In this case, auser puts the straw through the tape and takes in the temperaturecontrollable object 10 a in the accommodating section 110 through thehole.

The temperature controllable object 10 a may include coffee, soupe orthe like beverage, or food.

Meanwhile, a method of manufacturing the pouch 100 a according to thefourteenth exemplary embodiment will be described below with referenceto FIG. 25 and FIG. 28A to FIG. 28C.

First, the first temperature control space forming member 331, the firstsealing portion 241 and the first accommodating section film 112 arecombined to form the front side, i.e., the outer skin. Here, thesealing-bar attachment-preventing portion 170 may also be placed on anupper side of the first sealing portion 241.

If the first temperature control space forming member 331 and thesealing-bar attachment-preventing portion 170 are made of the same PETfilm, the PET films are cut and arranged at predetermined positionsbefore combination, so that the first temperature control space formingmember 331 and the sealing-bar attachment-preventing portion 170 can bearranged.

A back outer skin opposite to the front outer skin is formed with thepouch stand 790 therebetween. The back outer skin is symmetrical to thefront outer skin with the pouch stand 790 therebetween, and the secondaccommodating section film 114, the second sealing portion 243 and thesecond temperature control space forming member 332 are arranged insequence from the upside.

Here, the temperature control agent 131 may be inserted between thefirst sealing portion 241 and the first temperature control spaceforming member 331 and between the second sealing portion 243 and thesecond temperature control space forming member 332.

Meanwhile, the first and second temperature control space formingmembers 331, 332, the temperature control agent 131 and the sealing-barattachment-preventing portion 170 may be wored by the following process.That is, in more detail, the pouch stand 790, the first and secondaccommodating section films 112, 114 and the first and second sealingportions 241, 243 are first sealed in the form of an envelope excepttheir upper regions, and then the first and second temperature controlspace forming members 331, 332 and the sealing-bar attachment-preventingportion 170 are arranged on the outer side of the envelop and thensecondarily sealed up.

In the state of being combined as shown in FIG. 28A, the edges of theother regions D2, D3 and D4 are sealed up except the edge D1corresponding to an upper opening of the contents-accommodating space asshown in FIG. 28B. At this time, the sealing may be achieved by thermaladhesion using the sealing bar heated within a predetermined secondtemperature range. Thus, the first and second accommodating sectionfilms 112, 114 form the contents-accommodating space 116.

At this time, the predetermined second temperature range may be 230° C.or higher and 300° C. or lower.

Next, the upper end region L of the first temperature control spaceforming member 331 is thermally adhered to the first sealing portion 241and the first accommodating section film 112 by the sealing bar heatedwithin a predetermined first temperature range. In more detail, theregion to be sealed by the sealing bar is a predetermined section S5from a position spaced apart by a predetermined width K1 from the upperend 331 a of the first temperature control space forming member 331toward the temperature control agent 331.

Here, the sealing of the sealing bar is not performed up to a sectionspaced part by a predetermined width w from the upper end 331 a of thefirst temperature control space forming member 331. This regioncorresponds to the foregoing grip portion 150. The center region upperend portion 331 b of the temperature control space forming member 331 isprovided to protrude so that the grip portion (see 150 in FIG. 1) can beformed in the form of the protruded center portion.

Here, the first temperature range may be 150° C. or higher and 220° C.or lower.

Since the first temperature range is lower than the second temperaturerange, the sealing region J sealed up by the sealing bar of the firsttemperature control space forming member 331 within the firsttemperature range has a thermal adhesive strength sealing weaker thanthose of the edge regions (refer to D1, D2, D3, D4 in FIG. 28B) sealedup by the sealing bar of the second temperature range.

The sealing region J of the first temperature control space formingmember 331 corresponds to the foregoing liquid reactant entrance 337.Accordingly, a user can easily open the liquid reactant entrance 337having a relatively weak thermal adhesive strength.

After sealing up the sealing region J of the first temperature controlspace forming member 331, the edge region D1 is not being sealed butopened so that the temperature controllable object can be insertedthrough such an opened opening.

Next, after the temperature controllable object is completely inserted,the opened edge region D1 is thermally adhered by the sealing bar heatedwithin the second temperature range.

At this time, the predetermined second temperature range may be 230° C.or higher and 300° C. or lower.

Meanwhile, the method of thermally adhering the second temperaturecontrol space forming member 332 to the second accommodating sectionfilm 114 and the second sealing portion 243 is the same as that for thefirst temperature control space forming member 332, and the repetitivedescriptions thereof will be avoided.

Meanwhile, in the foregoing, the temperature control agent 131 isinserted between the first temperature control space forming member 331and the first sealing portion 241 and the edges D2, D3, D4 are sealedup, and then the temperature controllable object is filled in theaccommodating space between the first and second accommodating sectionfilms 112, 114.

However, in the case where the edges D2, D3, D4 of the first and secondaccommodating section films 112, 114 first undergo the sealing work, andthen the first and second sealing portions 241, 243 and the first andsecond temperature control space forming members 331, 332 undergo thefollowing sealing process, the contents-accommodating space is alreadyformed, and therefore the accommodating space is first filled with thetemperature controllable object and then filled with the temperaturecontrol agent 131. Accordingly, the sealing work for the edges D2, D3,D4 may be performed once again. That is, the contents filling andsealing process and the temperature control agent filling and sealingprocess may be exchanged in order.

Here, if the temperature controllable object (i.e., the contents) iscoffee, soup or the like liquid food needed to be sterilized, thecontents filling and sealing processes may be previously performed tothe temperature control agent filling and sealing process so as to makethe contents filling process more safety.

The sealing of the upper end edge D1 of the pouch may be performed afterthe temperature controllable object (i.e., the contents) is filled. Asnecessary, the upper end edge D1 may not be sealed if the temperaturecontrollable object (i.e., the contents) is hardly affected by anexternal environment or if there is no need of sealing thecontents-accommodating space because its expiration date is short.

Meanwhile, a method of manufacturing the pouch will be described belowwith reference to FIG. 18 to FIG. 21 and FIG. 29.

First, the contents-accommodating section 110 capable of accommodatingthe contents therein, the temperature control space forming member 132arranged in at least one side between the front and back sides of thecontents-accommodating section 110 and having the upper end lower thanthat of the contents-accommodating section, and at least one sealingportion 140 inserted between the temperature control space formingmember and the contents-accommodating section are combined (S10).

Then, the upper end region of the temperature control space formingmember 132 with the sealing portion 140 is thermally adhered to thecontents-accommodating section 110 by the sealing bar heated at thefirst temperature (S20). Here, the upper end region, which correspondsto the liquid reactant entrance 136 of the temperature control spaceforming member 132, seals up the liquid reactant entrance 136.

Here, the first temperature may be 150° C. or higher and 220° C. orlower. If the first temperature for heating the sealing bar to thermallyadhere the upper end region is lower than 150° C., the thermal adhesivestrength of the liquid reactant entrance 136 is so weak that the sealingof the temperature control space 134 is deteriorated between thetemperature control space forming member 131 and thecontents-accommodating section 110, thereby allowing foreign materials(e.g., moisture or the like) to be introduced.

On the other hand, if the first temperature is higher than 220° C., thethermal adhesive strength of the liquid reactant entrance 136 is sostrong that it is difficult for a user to open the temperature controlspace 134.

Next, the temperature control agent 131 is inserted in the temperaturecontrol space forming member 131 and the contents-accommodating section140 (S30).

Next, the left and right sides and the lower sides of the temperaturecontrol space forming member 132 filled with the temperature controlagent 131 are thermally adhered to the contents-accommodating section110 by the sealing bar heated up to the second temperature (S40).

Here, the second temperature may be 230° C. or higher and 300° C. orlower.

Here, the first temperature is lower than the second temperature. Asdescribed above, this is to make a user easily open the temperaturecontrol space 134 while keeping its sealing as the thermal adhesivestrength of the liquid reactant entrance 136 expected to be open isweaker than the other portions (i.e., the left, right and lower edges).

Meanwhile, the combination of S10 includes primarily sealing the left,right and lower edges of the contents-accommodating section 110 and thesealing portion 140 so that the upper end of the contents-accommodatingsection 110 can be open, by combining the contents-accommodating section110 and the sealing portion 140 (S11); and combining the temperaturecontrol space forming member 132 to the front side of the primarilysealed sealing portion 140 (S12). Thus, the accommodating space 116 isformed to accommodate the temperature controllable object 10 in thestate that the upper end of the contents-accommodating section 110 isopened.

Here, in the primarily sealing (S11), only the contents-accommodatingsection 110 may be combined and sealed without the sealing portion 140.In this case, the sealing portion 140 together with the temperaturecontrol space forming member 132 may be sequentially combined to thecontents-accommodating section 110 in the combination (S12).

Meanwhile, the operation of putting the temperature controllable object10 in the accommodating space 116 formed by the primarily sealing may beperformed between the primarily sealing (S11) and the combination of thetemperature control space forming member 132 (S12).

As necessary, the operation of putting the temperature controllableobject 10 may be performed after the operation S40 of thermally adheringthe left, right and lower end regions of the temperature control spaceforming member 132.

Of course, this isnothing but illustrative. The first accommodating section film 112 mayinclude a combination film of various materials, or as necessary includea film of a single material. The second accommodating section film 2114may be made of the same material as that of the first accommodatingsection film 2112.

The first accommodating section film 2112 and the second accommodatingsection film 2114 form an envelope shape as the other side and bothsides connecting one side and the other side are adhered and sealed soas to open one side. As the first accommodating section film 2112 andthe second accommodating section film 2114 are adhered, theaccommodating space 2116 accommodating the temperature controllableobject 10 is formed. Trough an opening side of the accommodating section2110, the temperature controllable object 10 is filled in theaccommodating space 2116, and the opening side is sealed up by thesealing-bar attachment-preventing portion 2170 to be described laterafter the temperature controllable object 10 is completely filled.

The temperature controller 2130 may be formed at one side between bothsides of the accommodating section 2110.

Here, the reactant 131 bmay be replaced or changed by other substances as long as it canexothermally react with the liquid reactant w.

On the other hand, the reactant 2131 b may include at least one as theheat absorption agent among ammonium nitrate (NH4NO3), sodium acetate(CH3COONa) and (urea). Of course, the reactant 131 b may be replaced orchanged by other substances as long as it can endothermally react withthe liquid reactant w.

The reactant accommodating section 2131 a accommodates the reactant 2131b. The reactant accommodating section 131 a includes a body 2131 a 1 anda partition 2131 a 2. The reactant accommodating section 2131 a isprovided as an absorption fabric to quickly absorb the liquid reactantw.

The body 2131 a 1 is provided to accommodate the reactant 2131 b. Here,the body 2131 a 1 according to an exemplary embodiment is partitionedinto four accommodating regions by the partition 2131 a 2. Thus, thereactant 2131 b is accommodated in each of the plurality ofaccommodating regions partitioned by the partition 2131 a 2, therebypreventing the reactant 2131 b from being leaning by its own weight.Also, the reactant 2131 b is accommodated in each of the plurality ofaccommodating regions, and thus the divided reactant 2131 b individuallycontacts the liquid reactant W1, thereby making a temperature controlreaction quickly.

The temperature control space forming member 2132, as shown in FIG. 30,is arranged in a lower side rather than an upper end of thecontents-accommodating section 2110. In more detail, the upper end ofthe temperature control space forming member 2132 is lower than theupper end of the contents-accommodating section 2110.

The temperature control space forming member 2132 includes a liquidreactant entrance 2136 through which the liquid reactant container 2190is taken out from the temperature control space 2134 and the liquidreactant W1 contained in the liquid reactant container 2190 is put in.

The temperature control space forming member 2132 together with thefirst accommodating section film 2112 forms the temperature controlspace 2134 to accommodate the temperature control agent 2131 and theliquid reactant container 2190. The temperature control space 2134 is aspace where the exothermic or endothermic reaction occurs when theliquid reactant W1 contained in the liquid reactant container 2190 isinserted, and has a margin space to accommodate the liquid reactant W1in addition to the temperature control agent 2131.

Here, the temperature control space forming member 2132 may be made of atransparent synthetic resin film so that the liquid reactant W1, theliquid reactant container 2190 and the temperature control agent 131 tobe inserted can be checked by naked eyes. Of course, the temperaturecontrol space forming member 2132 may be made of the transparentsynthetic resin film with regard to only a part that can be checked bynaked eyes. Of course, the temperature control space forming member 132may be partially made of the transparent synthetic resin film checkableby naked eyes. Of course, checkability by naked eyes is optional, andthus an opaque film may be used as necessary. The temperature controller2130 may be lower than the accommodating section 2110 so that an upperopening of the accommodating section 2110 for inserting the temperaturecontrollable object 10 can be exposed. According to an exemplaryembodiment, the height of the temperature control space forming member132 may be eight tenth with respect to the height of the accommodatingsection 110.

The temperature control space forming member 2132 may have an upper endlower than that of the contents-accommodating section 2110.

The temperature control space forming member 2132 according to anexemplary embodiment may be arranged to have a height from the lower endof the contents-accommodating section 2110 to the upper end of thetemperature control space forming member 2132, which is lower by 20%than the height from the same position to the upper end of thecontents-accommodating section 2110.

The temperature control space forming member 2132 may be made of theplastic film. For example, the temperature control space forming member132 may be the plastic film where a PET film having a thickness of 12 μmand a CPP film having a thickness of 60 μm are combined. Of course, thisis nothing but illustrative. Alternatively, the plastic film may be acombination film where films of various well-known substances arecombined or a single material film.

The liquid reactant container 2190 as shown in FIG. 34 includes a liquidreactant the accommodating section 2191 forming the accommodating spaceto accommodate the liquid reactant W1; a liquid reactant outlet 2193through which the accommodated liquid reactant flows out; and a liquidreactant container cutting portion 2195 for cutting the liquid reactantoutlet 2193.

The liquid reactant container 2190 may be made of soft or hard plasticfilm. According to an exemplary embodiment, the liquid reactantcontainer 2190 may be an envelope made of a soft plastic film. Asnecessary, the liquid reactant container 2190 may be achieved by sealinga hard plastic film (or plate) and a soft plastic film with each other.

The liquid reactant outlet 2193 may have a width narrower than theliquid reactant the accommodating section 2191. Thus, through the liquidreactant outlet 2193 having a relatively narrow width, the liquidreactant W1 can easily flow out in a predetermined direction.

The liquid reactant container cutting portion 2195 may include a notchformed at one side of the liquid reactant outlet 2193. The notch may bereplaced by a cutting groove formed along the cutting direction.Besides, the notch may have various shapes as long as it can be cut witha hand gripping the liquid reactant outlet 2193.

The liquid reactant container cutting portion 2195 may be cut when auser artificially applies shear force in a width direction with his/hertwo hands. Thus, it is possible to prevent the liquid reactant containercutting portion 2195 from being cut by mistake while carrying the pouch22100 a.

The liquid reactant insertion portion 2136 is coupled to thecontents-accommodating section 2110 by the sealing portion 2140 to bedescribed later, and closes the temperature control space 2134.

Also, the liquid reactant insertion portion 2136 is provided to open thetemperature control space 2134 closed by the sealing portion 2140 sothat the liquid reactant container 2190 can be taken out and the liquidreactant W1 contained in the liquid reactant container 2190 can be putin.

In more detail, the liquid reactant insertion portion 2136 can be spacedapart from the sealing portion 2140 or the first accommodating sectionfilm 2112 when force of not less than a predetermined magnitude isapplied, in order to take out the liquid reactant container 2190 fromthe temperature control space 2134 and put the liquid reactant W1 of theliquid reactant container 2190. Thus, the upper side of the temperaturecontrol space 2134 is opened so that the liquid reactant W1 can be putin the temperature control space 2134.

The sealing portion 2140 seals up the accommodating section 2110 and thetemperature controller 2130, specifically, the liquid reactant insertionportion 2136, thereby sealing up the temperature control space 2134.Here, the sealing portion 2140 seals up the accommodating section 2110and the liquid reactant insertion portion 2136 with predeterminedintensity of adhesion so that the temperature control space 2134 can beopened when force of not less than a predetermined magnitude is appliedfor spacing the liquid reactant insertion portion 2136 apart from theaccommodating section 2110. That is, when the liquid reactant insertionportion 2136 is pulled by force stronger than the adhesive strength ofthe sealing portion 2140, the temperature control space 2134 is opened.On the other hand, if force of not less than a predetermined magnitudeis not applied, the sealing due to the sealing portion 2140 ismaintained, thereby maintaining the sealed state of the temperaturecontrol space 2134

Here, the sealing portion 2140 may have an adhesive strength of not lessthan 2200 gf/cm² and not more than 5 kgf/cm². In experimental results,if the adhesive strength is less than 2200 gf/cm², the sealing may notbe maintained when the temperature controllable object 10 is filled andthen heated to expand the temperature control space 2134. On the otherhand, the adhesive strength is more than 5 kgf/cm², it is difficult fora regular adult to open the temperature control space 2134.

Preferably, the sealing portion 2140 may have a adhesive strength of 500gf/cm²˜3 kgf/cm².

According to an exemplary embodiment, the sealing portion 2140 is placedon the planar surface of the first accommodating section film 2112, andseals up between the liquid reactant insertion portion 136 of thetemperature controller 130 and the first accommodating section film2112. Thus, the sealing portion 2140 seals up between the firstaccommodating section film 2112 and the liquid reactant insertionportion 2136, and prevents foreign materials from being introduced intothe temperature control space 134 while the temperature controllableobject 10 is filled in the accommodating space 2116 of the accommodatingsection 2110 and then sterilized. Such sterilization is essential when aretort pouch is produced by putting stew, soup, boiled rice and the likeinstant foods into the pouch 2100.

Meanwhile, the sealing portion 2140 may be released from the sealingwith the liquid reactant insertion portion 2136 when force of not lessthan a certain magnitude is applied for inserting the liquid reactant W1into the temperature control space 1134 as temperature control isrequired for the temperature controllable object 10. Then, the liquidreactant insertion portion 2136 is opened to open the temperaturecontrol space 2134, so that the liquid reactant w can be inserted in thetemperature control space 2134. Accordingly, the exothermic orendothermic reaction occurs between the temperature control agent 2131and the liquid reactant W1.

Here, the sealing portion 2140 may include at least one among liquidadhesive for adhering the first accommodating section film 2112 and theliquid reactant insertion portion 2136, a solid adhesive tape, and aneasy peel film provided between the first accommodating section film2112 and the liquid reactant insertion portion 2136.

Here, the solid adhesive tape may be a film type tape, one or both sidesof which the adhesive is applied to.

The easy peel film couples both films thereof with predetermine thermaladhesion when heat of a predetermined temperature range is applied.Here, the coupling force or adhesion may be controlled by adjusting thetemperature range of heat applied to the easy peel film.

Here, the adhesive strength due to the sealing portion 2140 between theliquid reactant entrance 2136 and the accommodating section 2110 isweaker than contact strength between the temperature control spaceforming member 132 and the accommodating section 2110 besides the liquidreactant entrance 2136.

In more detail, the liquid reactant entrance 2136 is expected to beopened so as to insert the liquid reactant in the temperature controlspace 2134, and therefore the adhesive strength of the partial sealingportion C10 between the liquid reactant entrance 2136 and theaccommodating section 2110 may be weaker than the adhesive strength ofthe partial sealing portion C9 in a lateral edge between the temperaturecontrol space forming member 2132 and the accommodating section 2110.This may be achieved by changing the temperature range of the sealingbar used when sealing the partial sealing portions C9, C10. Suchtemperature range will be described later.

The upper end region of the temperature control space forming member2132 and the contents-accommodating section 2110 between which thesealing portion 2140 is interposed are may be thermally adhered by thesealing bar heated at the first temperature. Here, the upper end region,which corresponds to the liquid reactant entrance 2136 of thetemperature control space forming member 2132, seals up the liquidreactant entrance 2136.

Here, the first temperature may be 150° C. or higher and 220° C. orlower. If the first temperature of the sealing bar thermally adheringthe upper end regions is lower than 150° C., the thermal adhesivestrength of the liquid reactant entrance 2136 is so weak that thesealability of the temperature control space 2134 between thetemperature control space forming member 2131 and thecontents-accommodating section 2110 is deteriorated to thereby allowingexternal foreign materials (e.g., moisture or the like) to be introducedtherein.

On the other hand, if the first temperature is higher than 220° C., thethermal adhesive strength of the liquid reactant entrance 2136 is sostrong that it is difficult for a user to open the temperature controlspace 2134.

Meanwhile, the partial sealing portion C9 of the left, right and loweredge regions between the temperature control space forming member 2132and the contents-accommodating section 2110 may be thermally adhered bythe sealing bar heated at the second temperature.

Here, the second temperature may be 230° C. or higher and 2300° C. orlower.

Here, the first temperature is lower than the second temperature. Asdescribed above, this is to make a user easily open the temperaturecontrol space 134 while keeping its sealing as the thermal adhesivestrength of the liquid reactant entrance 136 expected to be open isweaker than the other portions (i.e., the left, right and lower edges).

Meanwhile, the grip portion 2150 is provided to allow a user to easilygrip the liquid reactant insertion portion 2136 of the temperaturecontroller 2130. The grip portion 2150 may be extended from the liquidreactant insertion portion 2136 and may be formed integrally with theliquid reactant insertion portion 2136.

The grip portion 2150 may protrude from the liquid reactant insertionportion 2136. The grip portion 2150 may be provided in the center regionof the liquid reactant insertion portion 2136. The grip portion 2150protrudes from the center region of the liquid reactant insertionportion 2136 and is gripped by a user. In particular, the grip portion2150 is gripped by a user and transfers a user's force to the liquidreactant insertion portion 2136 so that the liquid reactant insertionportion 2136 can be released from the accommodating section 2110. Tomake a user easily grip the grip portion 2150 and efficiently transferhis/her force, the grip portion 2150 may protrude from the centerportion of the liquid reactant insertion portion 2136.

Of course, the grip portion 2150 be plurally provided at both sides ofthe liquid reactant insertion portion 136.

As shown in FIG. 31, the upper end portions of the first and secondaccommodating section films 2112, 2114 are not sealed so that thetemperature controllable object 10 can be put into thecontents-accommodating section 2110 along the inserting direction B1 inthe state that the upper portion of the contents-accommodating section2110 is opened.

To heat or cool the temperature controllable object 10 accommodated inthe contents-accommodating section 2110, as shown in FIG. 33, a userfirst grips the grip portion 2150 and pulls the liquid reactant entrance2136 in a direction of F1, thereby spacing it apart from theaccommodating section 2110. At this time, if force of not less than apredetermined magnitude is applied for spacing the liquid reactantentrance 2136 apart from the accommodating section 2110, that is,stronger than the adhesive strength due to the sealing portion 2140, theliquid reactant entrance 2136 is opened. As described above, the thermaladhesive strength in the sealing region C10 due to the sealing portion150 is weaker than the thermal adhesive strength of the edge portion C9of the accommodating section 2110, and therefore the liquid reactantentrance 2136 can be more easily opened than other portions.

In the state that the temperature control space 2134 is being opened,the liquid reactant container 2190 is taken out from the temperaturecontrol space 2134 and the liquid reactant container 2190 is cut usingthe liquid reactant container cutting portion 2195 of the liquidreactant container 2190. From the cut liquid reactant container 2190,the liquid reactant is put into the temperature control space 2134.Accordingly, the exothermic or endothermic reaction occurs between theliquid reactant and the temperature control agent 2131 within thetemperature control space 2134, so that the temperature controllableobject 10 accommodated in the accommodating space 2116 can be heated orcooled. As a proper amount of the liquid reactant contained in theliquid reactant container 2190 reacts with the temperature control agent2131, the optimal exothermic or endothermic reaction may occur.

After a lapse of predetermined time, a user uses the grip portion 2180to cut open the upper end of the accommodating section 2110. Thus, auser takes in, takes out or uses the heated or cooled temperaturecontrollable object 10 through the accommodating section 2110 having theopened upper portion.

Meanwhile, the foregoing illustrates that the lateral edges D6 of thefirst accommodating section film 2112 and the second accommodatingsection film 2114 of the contents-accommodating section 2110 aredirectly sealed up. As necessary, the cross section of the lateral edgesmay be creased like “

” so that a user can more easily grip the lateral side of the pouch2100. This may be achieved by interposing a separate film between thelateral edges of the first accommodating section film 2112 and thesecond accommodating section film 2114 and thus broadening both edges.

Eighteenth Exemplary Embodiment

A pouch 2200 according to the eighteenth exemplary embodiment, as shownin FIG. 35 to FIG. 37 includes a contents-accommodating section 2210having a contents-accommodating space S6 to accommodate the contents; atemperature controller 2220 provided in at least one side between thefront and back sides of the contents-accommodating section 2210 to heator cool the contents-accommodating section 2210; and a sealing portion2230 sealing up a liquid reactant entrance 2222 communicating thetemperature control spaces S7, S8 in the temperature controller 2220.

The contents-accommodating section 2210 includes a first accommodatingsection film 2211 and a second accommodating section film 2213 to formthe contents-accommodating space S6.

The first accommodating section film 2211 and the second accommodatingsection film 2213 may be made of a plastic film. In more detail, theplastic film may include polyethylene (PE), polypropylene (PP), or apolyethyelene terephthalate (PET). Besides, the first accommodatingsection film 2211 and the second accommodating section film 2213 may bemade of well-known synthetic resin films of various materials.

The temperature controller 2220 couples with the contents-accommodatingsection 2210, in more detail, couples with the contents-accommodatingsection 2210 so as to form the temperature control spaces S7, S8provided in at least one side between the front and rear sides withrespect to the contents-accommodating space S6.

FIG. 35 to FIG. 37 illustrate that the temperature control spaces S7, S8are formed in front and back, but not limited thereto. As necessary, thetemperature control spaces S7, S8 may be formed at only one side.

The temperature controller 2220 includes a second front film 2221coupled in the front of the contents-accommodating section 2210 andforming the temperature control space S7 in a front side; and a secondback film 2224 coupled in the back of the contents-accommodating section2210 and forming the temperature control space S8 in a back side.

The first temperature control space forming member 2221 and the secondtemperature control space forming member 2224 may be made of a plasticfilm such as polyethylene (PE), polypropylene (PP), or a polyethyeleneterephthalate (PET). Besides, the first temperature control spaceforming member 2221 and the second temperature control space formingmember 2224 may be made of well-known synthetic resin films of variousmaterials.

Here, the temperature control spaces S7, S8 are isolated from thecontents-accommodating space S6.

The front and back temperature control spaces S7, S8 can communicatewith each other through a communication space S9. The communicationspace S9 may be formed by arranging the contents-accommodating section2210 so that the lower end portion 2211 c of the contents-accommodatingsection 2210 can be spaced apart from the lower end portion D6 of thetemperature controller 2220. In this case, the lower end portion D6 ofthe temperature controller 2220 is a part where the respective lower endportions of the first temperature control space forming member 2221 andthe second temperature control space forming member 2224 are coupled byultrasonic waves or thermal welding. Of course, coupling between theplastic films may be achieved various well-known methods besides theforegoing ultrasonic waves or thermal welding.

Meanwhile, the contents-accommodating section 2210 and the temperaturecontroller 2220 may be coupled with each other at left and right endportions D6, D7 by ultrasonic waves or thermal welding.

The temperature controller 2220 includes a plurality of temperaturecontrol agents 2223, 2225 respectively arranged in the plurality oftemperature control spaces S7, S8.

As described above, if the temperature control spaces, S8 are formed atonly one side between front and back sides, the temperature controlagents 2223, 2225 may be arranged at only one corresponding side.

Here, the temperature control agents 2223, 2225 includes heatingelements 2223 a, 2225 a to exothermically react with the liquidreactant, and absorption fabrics 2223 b, 2225 b surrounding the heatingelements 2223 a, 2225 a and absorbing the liquid reactant to make theexothermic reaction smoothly.

As necessary, the absorption fabrics 223 b, 225 b may be omitted.

Also, a heat absorption agent endothermically reacting with the liquidreactant may be used instead of the heating elements 2223 a, 2225 a. Theheating element and the heat absorption agent react with the liquidreactant to heat and cool the contents accommodated in thecontents-accommodating space S6.

The heating element may include at least one among calcium oxide,calcium hydroxide, magnesium chloride, iron, and aluminum. Of course,the foregoing substances may be replaced or changed by other substancesas long as it can react with the liquid reactant.

The heat absorption agent may include at least one of ammonium nitrate(NH4NO3), sodium acetate and urea.

Here, the plurality of temperature control agents 2223, 2225 may allinclude only the heating elements, or only the heat absorption agent.

As necessary, in the plurality of temperature control agents 2223, 2225,the front temperature control agent 2223 may include only the heatingelement, and the back temperature control agent 2225 may include onlythe heat absorption agent. In this case, the front and back temperaturecontrol spaces S7, S8 may not communicate with each other but isolatedfrom each other with the contents-accommodating space S6 therebetween.

The temperature controller 2220 may further include the liquid reactantcontainer 2190 arranged in the temperature control spaces S7, S8.

If the temperature control spaces S7, S8 communicate with each other,the liquid reactant container 2190 may be provided in only thetemperature control space S7 formed with the liquid reactant entrance2222 to be described later. If the liquid reactant entrances 2222 arerespectively formed at both sides of the plurality of temperaturecontrol space S7, S8, the liquid reactant container 2190 may be providedin each of the temperature control spaces S7, S8.

The temperature controller 2220 may further include the liquid reactantentrance 2222 through which the liquid reactant container 2190 is takenout from the temperature control spaces S7, S8 and the liquid reactant(refer to W1 of FIG. 34) of the liquid reactant container 2190 is putin.

The liquid reactant entrance 2222 is sealed up by the sealing portion2230 so as to be openable.

Also, the liquid reactant entrance 2222 is arranged at a lower side ofthe contents-accommodating section 2210 rather than an upper endthereof. That is, an upper edge of the liquid reactant entrance 2222 islower than the upper end of the contents-accommodating section 2210 sothat a user can easily check the position of the liquid reactantentrance 2222 with his/here naked eyes.

The liquid reactant entrance 222 may be formed as a partial upper endsection G1 of the first temperature control space forming member 2221 ofthe temperature controller 2220 is not coupled with the firstaccommodating section film 2211. At this time, the first temperaturecontrol space forming member 2221 of the remaining upper end section D8may be permanently sealed up with the first accommodating section film2211.

Here, the liquid reactant entrance 222 the partial upper end section Gof the second front film 221. As necessary, the liquid reactant entrance222 may be formed in the entire upper end section of the second frontfilm 221.

Here, the drawings illustrate the liquid reactant entrance 2222 isformed in the partial upper end section G1 of the first temperaturecontrol space forming member 2221. As necessary, the liquid reactantentrance 222 may be formed in the entire upper end section of the firsttemperature control space forming member 2221.

Also, the height of the liquid reactant entrance 2222 from the lower endof the pouch may be relatively greater than that of the remainingsection D8 of the first temperature control space forming member 2221from the lower end of the pouch 2200. Of course, the liquid reactantentrance 2222 may have the same height as the remaining section D8 ofthe first temperature control space forming member 2221.

The pouch 2200 may include a grip portion 2222 a extended frontward sothat a user can easily grip the liquid reactant entrance 2222 withhis/her hand. Thus, a user can easily grip and open the liquid reactantentrance 2222.

Here, the grip portion 2222 a may be as shown in FIG. 37 formed to befolded down from the first accommodating section film 2211.

As necessary, instead of the grip portion 2222 a of FIG. 37, the upperend of the first temperature control space forming member 2221 may beprovided as it is spaced apart from the contents-accommodating section2210, specifically from the first accommodating section film 2211 by apredetermined space K. Thus, a user puts his/her fingers in the spaceand broadens the liquid reactant entrance 2222, thereby opening theliquid reactant entrance 2222.

Meanwhile, the sealing portion 2230 seals up the liquid reactantentrance 2222 as long as the liquid reactant entrance 2222 is not spacedfrom the contents-accommodating section 2210 by force of not less than apredetermined magnitude. Thus, it is possible to prevent foreignmaterials from entering the liquid reactant entrance 2222 while thecontents is put into and sterilized in the contents-accommodatingsection S6 of the pouch 2200. Such sterilization is essential when aretort pouch is produced by putting stew, soup, boiled rice and the likeinstant foods into the pouch 2200.

Accordingly, the pouch 2200 according to an exemplary embodimentfacilitates the manufacture of the retort pouch.

As shown in FIG. 37, the sealing portion 2230 may be provided betweenthe first temperature control space forming member 2221 and the firstaccommodating section film 2211 at a side lower than the grip portion2222 a of the liquid reactant entrance 2222.

The sealing portion 2230 may be provided to allow opening between thefirst accommodating section film 2211 and the first temperature controlspace forming member 2221 when force of not less than a predeterminedmagnitude is applied thereto. In other words, if external force of notless than a predetermined magnitude is applied, the sealing portion 2230may open the liquid reactant entrance 2222. Thus, if a user grips andthen pulls the grip portion 2222 a by force of not less than apredetermined magnitude, the liquid reactant entrance 2222 is opened.

A user takes out and cuts the liquid reactant container 2190 from theopen liquid reactant entrance 2222, and puts the liquid reactant (referto W1 of FIG. 34, for example, water) into the temperature control spaceS7, thereby heating or cooling the contents accommodated in thecontents-accommodating space S6.

Here, the liquid reactant (refer to W1 of FIG. 34) put into thetemperature control space S7 causes the exothermic or endothermicreaction while moving to another temperature control space S8 throughthe communication space S9.

Also, since the liquid reactant entrance 2222 is easily opened to putthe liquid reactant, it is convenient for a user.

The sealing portion 2230 may be made of the same material as the sealingportion 2140 of the foregoing seventeenth exemplary embodiment. In moredetail, the sealing portion 2230 may include at least one among liquidadhesive, a solid adhesive tape, and an easy peel film arranged betweenthe first accommodating section film 2112 and the liquid reactantinsertion portion 2136.

As necessary, the sealing portion 2230 may be formed by fusing the firstaccommodating section film 2211 and the first temperature control spaceforming member through thermal welding or ultrasonic waves. At thistime, the first accommodating section film 2211 and the firsttemperature control space forming member 2221 may be fused to such anextent as to be separated from each other when the sealing portion 2230receives external force of a predetermined magnitude.

Of course, the sealing portion 2230 may be varied as long as it can sealup the liquid reactant entrance and prevent foreign materials, such asliquid (e.g., water), from being introduced therein if there is noexternal force of not less than a predetermined magnitude.

Meanwhile, the pouch 2200 may further include a ziplock 2260 toselectively seal up the upper portion of the contents-accommodatingsection 2210. As necessary, the ziplock 2260 may be omitted.

The ziplock 2260 includes a female zipper 2261 formed inside the firstaccommodating section film 2211 and a male zipper 2263 formed inside ofthe second accommodating section film 2213. Of course, the positions ofthe female zipper 2261 and the male zipper 2263 may be exchanged.

Also, various well-known sealing means may be employed instead of theziplock 2260 as long as it can selectively seal up thecontents-accommodating section 2210.

Meanwhile, the pouch 2200 may further include a transparent window 2215,2216, 2217 for checking whether the contents-accommodating space S6 issealed up or not. That is, the defect of the contents-accommodatingsection 210 can be determined by naked eyes through the transparentwindows 2215, 2216, 2217.

As shown in FIG. 35, the transparent window 2215 may be arranged betweenthe liquid reactant entrance 2222 and the upper end of the firstaccommodating section film 2211. Through the transparent window 2215,contact between the first accommodating section film 2211 and thecontents accommodated therein is checked by naked eyes, and it is thuspossible to determine whether a product is defective or not. Forexample, if solid food is put into the contents-accommodating section2210 and then the contents-accommodating space S6 is vacuumized, it ispossible to determine by naked eyes through the transparent window 2215whether there is a trouble in the vaccumization.

Meanwhile, the transparent window 216 may be as shown in FIG. 35 andFIG. 36 formed in a lower portion of the pouch 2200. If the contentsaccommodated in the contents-accommodating section 2210 is liquid andthe liquid leaks out because the contents-accommodating section 2210 isdefective, it is possible to determine by naked eyes through thetransparent window 2216 of the lower portion whether the product isdefective or not. To make it easier to determine through the transparentwindow 2216 of the lower portion whether the contents-accommodatingsection 2310 is sealed up or not, a corresponding region of the firsttemperature space forming member 2221 formed with the transparent window2216 may be transparently formed, but a corresponding region of thefirst temperature space forming member 2221 may be opaque. For example,the first temperature space forming member 2221 may be entirely made ofa transparent film, while the first accommodating section film 2211 maybe entirely made of an opaque film.

Also, the transparent window 2217 formed in a vertical direction may beas shown in FIG. 35 formed at one side between left and right sides ofthe pouch 2200 along a lengthwise direction. Thus, a user leans thepouch 2200 and checks by his/her naked eyes through the transparentwindow 2217 whether the contents accommodated in thecontents-accommodating section 2210 leak out or not, thereby determiningwhether a product is defective or not.

The plurality of transparent windows 2215, 2216, 2217 are to checkwhether the contents-accommodating space S6 of thecontents-accommodating section 2210 is surely isolated from thetemperature control spaces S7, S8. If it is checked through theplurality of transparent windows 2215, 2216, 2217 that there is nodefect in a product, the contents of the contents-accommodating space S6is not affected by a byproduct produced by the exothermic or endothermicreaction within the temperature control spaces S7, S8.

The drawings show the plurality of transparent windows 2215, 2216, 2217,but the number and positions of the transparent windows 2215, 2216, 2217may be varied.

Meanwhile, the foregoing description illustrates that the liquidreactant entrance 2222 is formed at only one side between the front andback sides, but not limited thereto. Alternatively, the liquid reactantentrance 222 may be formed at both the front and back sides.

Nineteenth Exemplary Embodiment

The pouch 2200 a according to the nineteenth exemplary embodiment asshown in FIG. 38 and FIG. 39 includes the contents-accommodating section2210; the temperature controller 2220 and a sealing portion 2240.

The nineteenth exemplary embodiment is the same as the eighteenthexemplary embodiment except that the ziplock 2260 is omitted and thesealing portion 2240 is arranged in a different position.

The sealing portion 2240 of the nineteenth exemplary embodiment mayincludes an adhesive tape 2240 attached to the upper end outside of theliquid reactant entrance 2222 and sealing up the temperature controlspace S7. Thus, it is possible to prevent foreign materials (inparticular, liquid) from being introduced into the temperature controlspaces S7, S8 while contents are put into the contents-accommodatingsection S6 and sterilized after the upper end of thecontents-accommodating section S6 is sealed up.

Meanwhile, the adhesive tape 2240 includes a tape grip portion 2241extended so that its one side can be gripped. Thus, if a user pulls thetape grip portion 2241 and removes the adhesive tape 2240, the liquidreactant of the liquid reactant container 2190 accommodated in thetemperature control space S7 can be easily put into the pouch 2200 b.

The first gripportion 2352 may be arranged in the center region of the first liquidreactant insertion portion 2337, and the second grip portion 2354 mayalso be arranged in the center region of the second liquid reactantinsertion portion 2338. The first grip portion 2352 and the second gripportion 2354 have the same shape as the grip portion 2150 of theseventeenth exemplary embodiment. Of course, the first grip portion 2352and the second grip portion 2354 may have different shapes from that ofthe grip portion 2150 of the seventeenth exemplary embodiment.

As described above, the pouch 2300 according to the twentieth exemplaryembodiment accommodates two temperature control agents 2131 in twotemperature control spaces 2334, 2335 as opposed to the seventeenthexemplary embodiment. Accordingly, the pouch 2300 according to thetwentieth exemplary embodiment can more quickly control the temperatureof the temperature controllable object 10 than the pouch 2100 accordingto the seventeenth exemplary embodiment.

Meanwhile, the sealing portion 2140 includes the first sealing portion2141 for sealing the first temperature control space 2334, and thesecond sealing portion 2143 for sealing the second temperature controlspace 2335.

The first and second sealing portions 141, 143 may be made of the samematerial as the sealing portion 2140 according to the foregoingseventeenth exemplary embodiment.

The first and second sealing portions 2141, 2143 seal up between thefirst temperature control space forming member 2331 and the firstaccommodating section film 2112 and between the second temperaturecontrol space forming member 2332 and the second accommodating sectionfilm 2114 so that the first and second liquid reactant entrances 2337,2338 can be opened when force of not less than a certain magnitude isapplied to space the first and second liquid reactant entrances 2337,2338 apart from the contents-accommodating section 2110.

Here, as shown in FIG. 40, a user may use the first grip portion 2352and the second grip portion 2354 to open the first and secondtemperature control spaces 2334, 2335, respectively.

Thus, the exothermic or endothermic reaction occursin the first and second temperature control spaces 2334, 2335, therebyheating or cooling the temperature controllable object within theaccommodating space 2116.

Twenty-First Exemplary Embodiment

A pouch 2300 a according to a twenty-first exemplary embodiment as shownin FIG. 41 includes a contents-accommodating section 2110 a includingthe first accommodating section film 2112, the second accommodatingsection film 2114 and the spacing film 115 spaced apart from the pouchstand 2790; the temperature controller 230 provided with the pluralityof temperature control agents 2131 respectively arranged in the firstaccommodating section film 2112 and the second accommodating sectionfilm 2114; the sealing portion 2140 for sealing up one among theplurality of temperature control spaces 2234, 2235 accommodating theplurality of temperature control agents 2131; the grip portion 2150; thesealing-bar attachment-preventing portion 2170, and the pouch cuttingportion (refer to 2180 in FIG. 30).

The first and second accommodating section films 2112, 114 and thespacing film 115 of the contents-accommodating section 2110 a may be allprovided a single film. As necessary, they may be manufactured withindividually cut films and then sealed.

The temperature controller 2230 includes the first and secondtemperature control space forming members 2231, 2232 respectively sealedwith the first and second accommodating section films 2112, 114 to formthe first and second temperature control spaces 2234, 2234; theplurality of temperature control agents 2131 respectively accommodatedin the first and second temperature control spaces 2231, 2232; and theliquid reactant container 2190 accommodated in the first temperaturecontrol space 2231.

The first temperature control space forming member 2231 has an upper endarranged to be lower than the upper end of the contents-accommodatingsection 2110.

The first temperature control space forming member 2231 includes theliquid reactant entrance 2237 through which the liquid reactantexothermically or endothermically reacting with the temperature controlagent 2131 can be inserted in the first temperature control space 231.

The sealing portion 2140 is provided between the liquid reactantentrance 2237 and the first accommodating section film 2112 of the firsttemperature control space forming member 2231.

The liquid reactant entrance 2237, the sealing portion 2140 and thefirst accommodating section film 2112 are thermally adhered by heat tobe sealed.

When the upper ends of the first accommodating section film 2112 and thesecond accommodating section film 2114 are sealed up by the sealing barhaving a predetermined sealing temperature in order to seal up theupside of the contents-accommodating section 2110, the firstaccommodating section film 2112 may be attached to and not separatedfrom the sealing bar.

The sealing-bar attachment-preventing portion 2170 prevents the firstaccommodating section film 2112 from being attached to and not separatedfrom the sealing bar.

In more detail, the first accommodating section film 2112 is asdescribed above made of a single CPP film or a combination film wherethe CPP film is exposed. The CPP film may be sticked to and not wellseparated from the sealing bar, and to prevent this, the sealing-barattachment-preventing portion 2170 may be provided on the firstaccommodating section film 2112 contacting the sealing bar.

The PET substance may be used as a material not well attached to thesealing bar. The sealing-bar attachment-preventing portion 2170 mayinclude a film of which a part exposed in a direction of pressing thesealing bar, i.e, frontward is combined with the PET film, or a singlePET film.

For example, the sealing-bar attachment-preventing portion 2170 may bethe same plastic film as the foregoing temperature control space formingmember 2132, where the PET film having a thickness of 12 μm and the CPPfilm having a thickness of 60 μm are combined. Here, the PET film has tobe arranged to be exposed frontward so that the PET film can contact thesealing bar.

Here, it is just illustrative that the PET is used as a material for thesealing-bar attachment-preventing portion 2170. The PET may be replacedby the plastic films of various well known materials as long as itcannot well attached to the sealing bar.

After the temperature controllable object (i.e., the contents) is filledwhile the accommodating section 2110 a is being opened, the sealing barheated at a predetermined temperature applies heat toward thesealing-bar attachment-preventing portion 2170 along the upper edges ofthe accommodating section 2110, thereby sealing up the upper end of theaccommodating section 2110. Accordingly, it is possible to prevent theaccommodating section 2110 from being attached to the sealing bar.

The sealing-bar attachment-preventing portion 2170, the firsttemperature control space forming member 2231 and the second temperaturecontrol space forming member 2232 may be all made of the same material.For example, each of the sealing-bar attachment-preventing portion 2170,the first temperature control space forming member 2231 and the secondtemperature control space forming member 2232 may be the plastic filmwhere the PET film having a thickness of 12 μm and the CPP film having athickness of 60 μm are combined.

Meanwhile, the pouch cutting portion 2180 may be provided between theliquid reactant insertion portion 2237 and the sealing-barattachment-preventing portion 2170.

The pouch cutting portion 2180 may include a notch in a transversedirection at one or both sides of the contents-accommodating section2110 so that

the contents-accommodating section 2110 can be torn when transverseforce of not less than a certain magnitude is applied.

The cutting portion may be arranged in a relatively thin position sothat the pouch cutting portion (refer to 2180 in FIG. 30) can be easilytorn through the notch.

In more detail, as shown in FIG. 41, the sealing-barattachment-preventing member 2170 and the liquid reactant insertionportion 2237 may be spaced apart from each other so that a cuttingregion A7 where the pouch cutting portion (refer to 2180 in FIG. 30)with the notch is provided can be relatively thin.

That is, the cutting region A7 includes only the first accommodatingsection film 2112 and the second accommodating section film 2114, and itis therefore thinner than three layered films of the sealing-barattachment-preventing member 170, the first and second accommodatingsection films 2112, 2114 provided at the upper side of thecontents-accommodating section 2110.

Also, total four films of the temperature control space forming member2231, the sealing portion 2140, the first accommodating section film2112 and the second accommodating section film 2114 are provided underthe cutting region A7, and therefore the cutting region A7 having twolayered films is relatively thin. Thus, the contents-accommodatingsection 2110 a can be more easily cut by the pouch cutting portion (see2180 in FIG. 30) formed in the cutting region A7.

To heat or cool the temperature controllable object, a user grips thegrip portion 2150 and applies force to the liquid reactant entrance2237, thereby opening the first temperature control space 2234. Further,the liquid reactant container 2190 is taken out and cut from the openfirst temperature control space 2234, and the liquid reactant isinserted in the opened first temperature control space 2234. The liquidreactant put into the first temperature control space 2234 is introducedinto a second temperature control space 235 through a communicationspace H1 between the liquid reactant

the accommodating section 2110 and the pouch stand 2790. Thus, theexothermic or endothermic reaction can occur between the liquid reactantand the temperature control agent 2131 within even the secondtemperature control space 2235.

In the case of the pouch 300 b according to the twenty-first exemplaryembodiment, even though a user opens not both the temperature controlspaces 2234, 2235 but one of them to insert the liquid reactant, theinserted liquid reactant can be transferred to the unopened space.Accordingly, it is convenient for a user.

Meanwhile, the sealing-bar attachment-preventing portion 2170 and thepouch cutting portion 2180 described above are not essential, and all ora part of the foregoing elements 2170, 2180 may be omitted.

Twenty-Second Exemplary Embodiment

The pouch 2100 b according to the sixth exemplary embodiment as shown inFIG. 42 includes the contents-accommodating section 2110, thetemperature controller 2130, the sealing portion 2240, the grip portion2150, the sealing-bar attachment-preventing portion 2170 and the cuttingportion (see 2180 in FIG. 30).

The pouch 2100 b according to the twenty-second exemplary embodiment isdifferent from the pouch 2100 of the seventeenth exemplary embodiment inthe shape of the sealing portion 2140 according to the seventeenthexemplary embodiment.

The sealing portion 2240 may be provided to cover the entire of thefirst accommodating section film 2112 of the contents-accommodatingsection 2110.

In the case of the pouch 2100 according to the seventeenth exemplaryembodiment, the sealing portion 2140 has a predetermined width as shownin FIG. 31. On the other hand, the sealing portion 2240 according to theeighth exemplary embodiment is provided to cover the entire front sideof the contents-accommodating section 2110.

Here, the sealing portion 2240 may include at least one among the liquidor solid adhesive tape for adhesion between the first accommodatingsection film 2112 and the liquid reactant insertion portion 2136, andthe easy peel film arranged between the first accommodating section film2112 and the liquid reactant insertion portion 2136.

Here, the solid adhesive tape may be a film type tape, one or both sidesof which the adhesive is applied to.

The easy peel film couples both films thereof with predetermine thermaladhesion when heat of a predetermined temperature range is applied.Here, the coupling force or adhesion may be controlled by adjusting thetemperature range of heat applied to the easy peel film.

In the case of the twenty-second exemplary embodiment, the sealingportion 2240 is provided to cover the entire of the first accommodatingsection film 2112, and therefore there is no need of position controlwork for positioning the sealing portion 2240 to a certain positionbetween the liquid reactant entrance 2136 and the first accommodatingsection film 2112. For reference, in the case of the sealing portion2140 according to the seventeenth exemplary embodiment shown in FIG. 31,it is positioned at only a specific portion, and therefore there is aneed of work for positioning the sealing portion 2140 to thecorresponding position.

Twenty-Third Exemplary Embodiment

A pouch 1000 according to a twenty-third exemplary embodiment as shownin FIG. 43 and FIG. 44 includes a contents-accommodating section 1100for accommodating contents, and a temperature controller 1200 providedwith temperature control agent 1210 and the liquid reactant insertionportions 1230, 1240.

The contents CA1 may include retort pouch such as solid boiled rice,Bibimbap, liquid soup, stew or dry milk; a pad containing medicine fortaking a hot massage or a cold massage, or a mask pad containing beautyingredients. Besides, the contents may be variously selected as long asit has to be instantly heated or cooled. Besides the foregoing retortpouch, the food needed for sterilization for prolong expiration date mayalso be included in the contents CA1 regardless of the kind or types.

The contents-accommodating section 1100 may form acontents-accommodating space SP1 where the contents CA1 areaccommodated.

The contents-accommodating section 1100 includes the first accommodatingsection film 1110 and the second accommodating section film 1120.

The first accommodating section film 112 and the second accommodatingsection film 114 may be made of the plastic film.

In more detail, the first accommodating section film 1110 and the secondaccommodating section film 1120 may be made of the plastic film such aspolyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate(PET). Of course, the first accommodating section film 112 and thesecond accommodating section film 114 constituting the accommodatingsection 110 may be made of well-known synthetic resin films of variousmaterials.

For example, the first accommodating section film 1110 may include a CPPfilm having a thickness of 60 μm, an aluminum film having a thickness of9 μm, or a combination film between a nylon film having a thickness of15 μm and a CPP film having a thickness of 60 μm. Of course, this isnothing but illustrative. The first accommodating section film 1110 mayinclude a combination film of various materials, or as necessary includea film of a single material. The second accommodating section film 1120may be made of the same material as that of the first accommodatingsection film 1110. As necessary, the second accommodating section film1120 may be made of different materials from the first accommodatingsection film 1110.

The left, right and lower ends SA2, SA3, SA4 of the first accommodatingsection film 1110 and the second accommodating section film 1120 aresealed up to form the contents-accommodating space SP1.

The upper end of the contents-accommodating space SP1 may be opened toput the contents CA1 therein. After the contents CA1 is put in thecontents-accommodating space SP1, the upper end of thecontents-accommodating space SP1 may be sealed. A sealing method mayincludes a method of using the sealing bar to fuse two films 1110, 1120with heat, or a method of fusing two films 1110, 1120 with ultrasonicwaves or microwaves. Besides, if the contents are not food, two films1110, 1120 may be sealed up by adhesive or an adhesive film. Besides theforegoing sealing methods, well-known various sealing methods may beemployed.

As necessary, if the contents CA1 are solid food or a pad for beauty ortreatment, the upper end of the contents-accommodating space SP1 may notbe sealed. Also, in the case that food to be heated or cooled is putinto the contents-accommodating space SP1 of the pouch 1000 and thendirectly the liquid reactant is inserted in the temperature controlspace SP2 formed by the temperature controller 1200, the upper end ofthe contents-accommodating space SP1 may not be sealed.

As shown in FIG. 44, the temperature controller 1200 is arranged in afront side of the contents-accommodating section 1100 and forms thetemperature control space SP2. Of course, as necessary, the temperaturecontrollers 1200 may be arranged in the back side as well as the frontside, and thus form the temperature control space at opposite sides withthe contents-accommodating section 1100 therebetween.

The temperature controller 1200 includes the temperature control agent1210 to be accommodated in the temperature control space SP2; and thetemperature control space forming member 1220 forming the temperaturecontrol space SP2 where the exothermic or endothermic reaction occurs.

The temperature control agent 1210 reacts with the liquid reactant(refer to W2 in FIG. 45) put into the temperature control space SP2,thereby causing the exothermic or endothermic reaction. Here, Thetemperature control agent 1210 may include the liquid reactant (refer toW2 in FIG. 45).

The temperature control agent 1210 includes the reactant 1211exothermically or endothermically reacting with the liquid reactant(refer to W2 in FIG. 45) and the reactant accommodating section 1213.The reactant 1211 includes the heating element or the heat absorptionagent causing the exothermic or endothermic reaction.

The reactant 1211 may include at least one as the heating element amongcalcium oxide (CaO), calcium hydroxide (Ca(OH)2), magnesium chloride(MgCl2), iron (Fe) and aluminum (Al). Here, the reactant 1211 may bereplaced by various materials as long as it can exothermically reactwith the liquid reactant W2.

Meanwhile, the reactant 1211 may include at least one as the heatabsorption agent among ammonium nitrate (NH4NO3), sodium acetate(CH3COONa) and (urea). Of course, the reactant 1211 may be replaced orchanged by other substances as long as it can endothermally react withthe liquid reactant W2.

The reactant accommodating section 1213 accommodates the reactant 1211.The reactant accommodating section 1213 may be provided as an absorptionfabric to absorb or transmit the liquid reactant W2. As necessary, thereactant accommodating section 1213 may be made of various materialsthat can absorb or transmit the liquid reactant W2.

The temperature control space forming member 1220 is opposite to thefirst accommodating section film 1110 of the contents-accommodatingsection 1100 and forms the temperature control space 134 foraccommodating the temperature control agent 1210 therebetween.

The temperature control space forming member 1220 may be made of atransparent synthetic resin film so that the liquid reactant W2 and thetemperature control agent 1210 to be inserted can be checked by nakedeyes. Of course, the temperature control space forming member 1220 maybe partially made of the transparent synthetic resin film checkable bynaked eyes. Of course, checkability by naked eyes is optional, and thusan opaque film may be used as necessary.

The upper end sealing regions SA1 of the temperature control spaceforming member 1220 and the first accommodating section film 1110 may bealigned with each other and then sealed up as shown in FIG. 44. Asnecessary, the upper end of the temperature control space forming member1220 may be positioned lower than the upper end of the firstaccommodating section film 1110 m and the upper end of the temperaturecontrol space forming member 1220 may be coupled to the firstaccommodating section film 1110.

The temperature control space forming member 1220 maybe provided as theplastic film such as PP, PE, PET, etc. For example, the temperaturecontrol space forming member 1220 may include the plastic film where thePET film having a thickness of 12 μm and the CPP film having a thicknessof 60 μm are combined. Of course, this is nothing but illustrative.Alternatively, the plastic film may be a combination film where films ofvarious well-known substances are combined or a single material film.

Meanwhile, the temperature control space forming member 1220 is arrangedto be lower than the upper end of the contents-accommodating section1110, and includes the liquid reactant insertion portions 1230, 1240into which the liquid reactant (refer to W2 in FIG. 45) can be put.

The liquid reactant insertion portions 1230, 1240 includes a firstfolding portion 1230 where the temperature control space forming member1220 is folded outward; and a first cutting portion 1240 for cutting thefirst folding portion 1230.

Here, the first folding portion 1230 may be folded inward as opposed tothat shown in FIG. 44. In this case, the first folding portion 1230 maybe partially exposed to the outside so that a user can take out theinward folded first folding portion 1230 before cutting the firstfolding portion 1230.

The first folding portion 1230 may protrude to have an end beinggradually inclined downward as shown in FIG. 44. Thus, it is possible toprevent the liquid reactant remaining after the reaction from leakingout through the cut first folding portion 1230.

The first cutting portion 1240 may include notches respectively arrangedat opposite edges of the first folding portion 1230. As necessary, thenotch may be formed at only one side.

The first cutting portion 1240 may include a cutting groove (not shown)extended along a cutting direction instead of the shown notch. Toprevent foreign materials from being introduced into the temperaturecontrol space SP2 through the cutting groove (not shown), the cuttinggroove (not shown) may be not a slit completely penetrating thetemperature control space forming member 1220 but a groove where thetemperature control space forming member 1220 is relatively thin.

Meanwhile, the temperature control space forming member 1220 may furtherinclude a second folding portion 1250 to be expanded by vapor generatedby the exothermic reaction in the temperature control space SP2. Here,the second folding portion 1250 may be omitted as necessary.

Below, use of the pouch 1000 according to the foregoing twenty-thirdexemplary embodiment will be described with reference to FIG. 45 to FIG.47.

As described above, the contents CA1 may be put in by a manufacturer ormay be put in the opened contents-accommodating section 1100 of thepouch 1000 by a user. In the state that the contents CA1 to becontrolled with regard to temperature are accommodated in thecontents-accommodating section 1100, a user cuts the first foldingportion 1230 through the first cutting portion 1240.

Thus, as shown in FIG. 45, the first folding portion 1230 is dividedinto a first upper folding part 1231 and a first lower folding part1233. Thus, the temperature control space SP1 is opened. The liquidreactant W2 is put in between divided first upper and lower foldingparts 1231, 1233.

As shown in FIG. 46, the put liquid reactant exothermically orendothermically reacts with the temperature control agent 1210. Here, ifthe exothermic reaction occurs, vapor is generated and the generatedvapor is discharged to the outside through the divided first upper andfirst lower folding parts 1231, 1233 while expanding the second foldingportion 1250.

Here, even though an abnormal state that vapor is suddenly andexplosively generated happens during the exothermic process, it can bedamped as the second folding portion 1250 expands. Thus, it is possibleto prevent the temperature control space forming member 1220 from beingtorn as it cannot stand vapor pressure, and prevent the temperaturecontrol space SP2 from being opened in other sealing portion except theliquid reactant insertion portions 1230, 1240 and the liquid reactant W2from flowing out.

As necessary, a user may transfer the heated or cooled contents CA1 bythe exothermic or endothermic reaction to a separate external containerA9 in order to take it in. In this case, as shown in FIG. 47, the liquidreactant W3 remaining in the temperature control space SP2 after thereaction is blocked by the upper end sealing regions SA1 of thetemperature control space forming member 1220 and the firstaccommodating section film 1110 and does not leak out. As describedabove, the first folding portions 1231, 1233 protrude being inclineddownward, and thus the first folding portions 1231, 1233 are inclinedupward when the pouch 1000 is turned upside down as shown in FIG. 47,thereby further preventing the liquid reactant W3 from leaking out.

Here, the upper end sealing regions SA1 of the temperature control spaceforming member 1220 and the first accommodating section film 1110 areused as a liquid reactant leaking-out preventing portion.

Meanwhile, the foregoing is described under conditions that the liquidreactant is not accommodated in the pouch 1000, but not limited thereto.As necessary, the liquid reactant may be accommodated and sealed in thetemperature control space SP2 of the pouch 1000.

In more detail, as shown in FIG. 48, the liquid reactant portion 1300including the liquid reactant W2; and a liquid reactant bag 1310 forpacking the liquid reactant W2 may be provided inside the temperaturecontrol space SP2.

The liquid reactant bag 1310 may include an accommodating space portion1313 for forming the accommodating space to accommodate the liquidreactant W2; a liquid reactant discharging portion 1311 through whichthe accommodated liquid reactant W2 can be discharged; and a cut portion1314 for cutting the upper end of the liquid reactant dischargingportion 1311. The liquid reactant discharging portion 1311 may benarrower than the accommodating space portion 1313. Thus, the liquidreactant can be easily discharged toward a predetermined target.

The amount of liquid reactant for optimally reacting with thetemperature control agent 1210 is defined. If a general user is allowedto put the liquid reactant into the temperature control space SP2, theexothermic or endothermic reaction may not occur as originally designedsince a random amount of liquid reactant is put.

Thus, as necessary, the liquid reactant portion 1300 containing theoptimal amount of liquid reactant for reacting with the temperaturecontrol agent 1210 provided in the temperature control space SP2 may beinternally provided.

The liquid reactant portion 1300 together with the temperature controlagent 1210 may be placed in the temperature control space SP2. At thistime, the temperature control space SP2 may be sealed up in the statethat the liquid reactant portion 1300 and the temperature control agent1210 are both placed.

The liquid reactant portion 1300 is not open if a user artificially cutsthe cut portion 1314, and therefore the liquid reactant does not leakout from the liquid reactant bag 1310.

A method of using the pouch provided with both the liquid reactantportion 1300 and the temperature control agent 1210 is as follows. Usingthe first cutting portion 1240 shown in FIG. 43, the first foldingportion 1230 is cut to open the temperature control space SP2.

From the open temperature control space SP2, the liquid reactant bag1310 is taken out and its cut portion 1314 is cut. Then, the liquidreactant W2 contained in the liquid reactant bag 1310 is put into thetemperature control space SP2.

Thus, the exothermic or endothermic reaction occurs in the temperaturecontrol space SP2 so that the contents CA1 filled in thecontents-accommodating section 1110 can be heated or cooled.

Except for taking out and putting the liquid reactant portion 1300containing the liquid reactant, the other using methods are the same asthe foregoing pouch using method, and thus repetitive descriptions willbe avoided.

Meanwhile, the foregoing illustrates that the liquid reactant portion1300 is accommodated in the temperature control space SP2, but notlimited thereto. As necessary, the liquid reactant portion 1300 may bedetachably attached to the pouch 1000 by adhesive or the like on theouter surface. Besides, the liquid reactant portion 1300 may be coupledto the pouch 1000 in various forms as long as it can together with thepouch 1000 be carried.
